FIELDThis disclosure relates to ballistic resistant panel assemblies, and more particularly ballistic resistant panel assemblies wherein the ballistic resistant panel assemblies include plies of ballistic resistant material.
BACKGROUNDBallistic resistant panel assemblies have many applications of use for providing ballistic protection. One application of use for the ballistic resistant panel assembly is positioning them within a garment assembly to provide life-saving ballistic protection to a wearer. Ballistic resistant panel assemblies are strategically positioned within the ballistic resistant protective garment assembly to optimize protection to the wearer. Ballistic resistant protective garment assemblies that are worn under clothing of the wearer are referred to as concealable ballistic resistant protective garments and those worn outside of the clothing of the wearer are often referred to as a tactical ballistic resistant protective garment. Other applications of use for ballistic resistant panel assemblies include use with respect to hand-held shields, backpacks, extremity protection devices, vehicles, personnel enclosures and other application of uses where protection from ballistic projectiles is needed.
Ballistic resistant panel assemblies can be constructed from a wide variety of ballistic resistant materials. A ballistic resistant panel assembly can, for example, have a plurality of plies. These plies can be constructed of ballistic resistant fibers configured in a woven fabric. The fibers can be selected from a wide variety of high strength ballistic resistant fibers having a composition such as an aramid, an ultra-high molecular weight polyethylene (UHMWPE) or other like high strength fibers utilized for ballistic protection. The plies are woven in a select weave pattern such as utilizing a plain weave, sateen weave or other common weave pattern employed for woven plies used for constructing a ballistic resistant panel assembly. Other ply constructions, for example, have a composite laminate unidirectional fiber construction which utilizes fibers composed of an aramid, (UHMWPE) fibers or other high strength fibers, which are positioned in layers within the ply such that each layer has unidirectional orientation of the high strength ballistic resistant fibers. The layers are laminated together with a material such as for example a polyethylene resin. Yet other examples of utilizing ballistic resistant material can include having a hard plate construction made from one or more of a metal, ceramic, and/or aramid materials which are positioned within the ballistic resistant protective garment. Construction of a ballistic resistant panel assembly include utilizing one or more of these various materials and constructions depending on the performance that is needed.
Ballistic resistant panel assemblies, such as used in a protective body armor garment assembly or in other applications of use of ballistic resistant panels, utilize a plurality of plies. The plies are constructed of a plurality of woven fibers or of composite unidirectional fiber laminates. Upon impact of a ballistic projectile onto a ballistic resistant panel assembly proximate to a peripheral edge portion of the ballistic resistant panel, such impact, whether in a direction generally perpendicular to the ballistic resistant panel assembly or in an angular direction relative to the ballistic resistant panel assembly, can promote separation of the plies within the ballistic resistant panel assembly, a phenomenon not likely to occur in an impact location in a more central location of the ballistic resistant panel assembly.
With the ballistic projectile being slowed down by the ballistic resistant plies, the process of stopping the ballistic projectile can promote separation of the ballistic resistant plies positioned near the impact location proximate the peripheral edge of the ballistic resistant panel assembly. Separation of the ballistic resistant plies provides less resistance to the ballistic projectile which may have a component of movement toward the peripheral edge of the ballistic resistant panel assembly.
There is a need to provide enhanced integrity to a ballistic resistant panel assembly in the peripheral edge portion so as to reduce and/or prevent ply separation within the ballistic resistant panel assembly and to facilitate capture of the ballistic projectile thereby optimizing the ballistic resistant panel assembly performance. At the same time of providing enhanced integrity, one needs to consider not imparting unnecessary stiffness to the ballistic resistant panel assembly.

The features, functions, and advantages that have been discussed can be achieved independently in various embodiments or may be combined in yet other embodiments further details of which can be seen with reference to the following description and drawings.
As will be appreciated in the discussion herein, it is important to provide enhanced integrity to a ballistic resistant panel assembly proximate to a peripheral edge of the ballistic resistant panel assembly. Upon impact of a ballistic projectile proximate to the peripheral edge of the ballistic resistant panel, the enhanced integrity is needed to resist separation of the ballistic resistant plies proximate to the peripheral edge of the ballistic resistant panel and to facilitate capture of the ballistic projectile. An example of a ballistic resistant panel assembly that will be discussed herein as an example in which enhanced integrity is provided will be a front ballistic resistant panel assembly that is used within a ballistic resistant garment. The enhanced integrity discussed herein can be similarly applied to a back ballistic resistant panel assembly for a ballistic resistant garment or to other applicational uses of ballistic resistant panels, as mentioned earlier, such as used in association with hand-held shields, backpacks, extremity protection devices, vehicles, personnel enclosures and other applicational uses where ballistic projectile protection is needed.
The enhanced integrity of a ballistic resistant panel to be discussed herein will provide ballistic resistant plies of the ballistic resistant panel assembly to resist separation of ballistic resistant plies at a location proximate to the peripheral edge of a ballistic resistant panel assembly where impact of a ballistic resistant projectile has occurred and to facilitate capture of the ballistic projectile. Separation of the ballistic plies can occur with the ballistic projectile traveling either directly at the ballistic resistant panel assembly or traveling in an angular direction relative to the ballistic resistant panel. The enhanced integrity, which will be discussed herein, provides for binding together the ballistic resistant plies of the ballistic resistant panel proximate to the location of the impacting ballistic projectile which occurs at an edge portion of the ballistic resistant panel. Binding the ballistic resistant plies together resists separation of the ballistic resistant plies at the edge portion of the ballistic resistant panel assembly. The bound ballistic resistant plies provide a blocked pathway of the ballistic projectile which can have a component of movement toward the peripheral edge of the ballistic resistant panel assembly. The enhanced integrity additionally provides a binding layer secured to the ballistic resistant plies which encases the peripheral edges of ballistic resistant plies enclosing the peripheral edge of the ballistic resistant panel which further provides a blocked pathway of the ballistic projectile which has impacted the ballistic resistant panel and which has a component of movement toward the peripheral edge of the ballistic resistant panel assembly.
An example of a ballistic resistant panel assembly, for discussion herein, will be a front ballistic resistant panel assembly used in association with concealable body armor carrier 10, as seen in
Concealable carrier 10 is also secured to the wearer with use of side straps 26. Side straps 26 at one end 28 are secured to back garment enclosure 14 by way of stitching or by way of other common fixed securement methods. In this example, panel of flexible loop type fasteners 30 are secured to front garment enclosure 12 and straps 26 carry at least one panel of flexible hook type fasteners 32. With all four straps 26, in this example, positioned in a desired location, flexible hook type fasteners 32 are engaged with flexible loop type fasteners 30 positioned on front garment enclosure 12 providing the wearer a snug fit to wearer's torso.
Front ballistic resistant panel assembly 34 is positioned within front garment enclosure 12 and back ballistic resistant panel assembly 36 is positioned within back garment enclosure 14. Front ballistic resistant panel assembly 34 will be used as an example of a ballistic resistant panel assembly to which to employ the enhanced integrity to a ballistic resistant panel assembly, to be discussed herein, and which can be applied to other applications of use of ballistic resistant panels, as mentioned earlier, including that of back ballistic resistant panel assembly 34.

Another example of a construction for ballistic resistant plies 38 used for constructing ballistic resistant panel assembly 34 includes utilizing at least one of ballistic resistant plies 38 being constructed of composite unidirectional fiber laminate 50. A schematic example of a ballistic resistant ply 38 constructed of composite unidirectional fiber laminate 50 is shown in
At least one layer 52 has plurality of first fibers 54 and at least one layer 58 has plurality of second fibers 60. In this schematic example, plurality of first fibers 54 are held together in at least one layer 52 with typically a very low modulus matrix often referred to as an clastic binder resin which is similar for the construction of at least one layer 58 with respect to plurality of second fibers 60. The layers containing fibers, such as, at least one layer 52 and at least one layer 58 are positioned in a sandwich arrangement between typically thin films 64, 66 which are constructed for example of a polyethylene and are laminated together securing together in this example at least one layer 52 and least one layer 58, as seen in
A wide variety of constructions can be selected for ballistic resistant plies 38 in constructing ballistic resistant panel assembly 34 which may include woven fabrics, composite unidirectional fiber laminates, or a combination thereof, depending on the performance parameters required for a particular ballistic resistant panel assembly 34.
In referring to
As seen in
Ballistic resistant panel assembly 34 further includes a plurality of stitches 90, which includes thread member 88 which will be discussed further below. Plurality of stitches 90 extend through first portion 70 of binding tape 68 and third portion 80 of binding layer 68, as well as, extending through first ballistic resistant ply 72 and second ballistic resistant ply 82 of stack 40. In this example, plurality of stitches 90 also extend through any ballistic resistant plies 38 positioned between first and second ballistic resistant plies 72, 82, as seen in the example in
With binding together less than all 78 of ballistic resistant plies 38 in stack 40 with rows 92 of stitches 90, in this example, and encasing peripheral edges 69 of ballistic resistant plies 38 with binding layer 68 of less than all 78 of ballistic resistant plies 38 in stack 40, such construction provides less potential stiffening from being imparted to ballistic resistant panel assembly 34, in contrast to binding together all ballistic resistant plies 38 in stack 40. At the same time, such construction provides enhanced integrity to ballistic resistant panel 34 in providing resistance to separation of adjacent ballistic resistant plies 38 within less than all 78 of ballistic resistant plies 38 of stack 40 and with encasing the peripheral edges 69 of ballistic resistant plies 38 of less than all of 78 ballistic resistant plies 38. This construction thereby facilitates capture of a ballistic projectile within ballistic resistant panel assembly 34, which has impacted ballistic resistant panel assembly 34 proximate to peripheral stack edge 71 with binding together of ballistic resistant plies 38 within the less than all 78 of the ballistic resistant plies 38 by rows 92 of stitches 90, in the example shown in
In fabricating ballistic resistant panel assembly 34, the manufacturer can provide a sufficient number of ballistic resistant plies 38, with respect to less than all 78 of plurality of ballistic resistant plies 38, to slow down and resist further penetration of ballistic resistant panel assembly 34 for a particular level of threat. The less than all 78 of plurality of ballistic resistant plies 38 can be encased with binding layer 68 and stitched or otherwise bound together, as discussed herein. Depending on the threat level being addressed by ballistic resistant panel assembly 34, two to four or more rows 92 of stitches 90 can be employed which provide a binding of the less than all 78 ballistic resistant plies 38 and provide securement of binding layer 68 to less than all 78 of plurality of ballistic plies 38, encasing peripheral edges 69 of the less than all 78 ballistic resistant plies 38.
Capture of the ballistic resistant projectile which impacts ballistic resistant panel 34 is facilitated with the use of a strong thread member 88 used in the plurality of stitches 90 which is constructed of a strong material such as nylon, aramid, polyethylene or other comparably strong material. In this example, a nylon thread is used which is designated commercially as “Tex 70” and which is positioned in this example with eight stitches per inch. The size of the nylon or other material and the number of stitches can be varied to accommodate the strength of binding needed for confronting a particular level of threat. In addition to the strength of the thread and number of stitches employed, it is beneficial to employ a configuration of stitching which includes rows 92 of stitches 90 which extend along spaced apart from peripheral stack edge 71 of plurality of ballistic resistant plies 38 of ballistic resistant panel 34, as seen in the example shown in
This example of stitching shown in this first example of ballistic resistant panel assembly 34, in

A wide variety of stitches can be used such as straight, zigzag, chain, outline, running, satin, tack as well as many other commonly used stitches. The positioning of these types of stitches in rows 92 of stitches 90 spaced apart from one another and spaced apart from peripheral stack edge 71 of the plurality of ballistic resistant plies 38 provides sufficient binding of less than all 78 of ballistic resistant plies 38 and binding of binding layer 68 to less than all 78 of the ballistic resistant plies 38 to facilitate capture of ballistic projectile.
